That would be awesome man, thanks! let me check it out first to be sure.
Now that we are sharing pictures... Instead of loosing the engine mount, I'll cut a piece of the sidewall-lip, so I can insert a wrench extension. I did this on my daily to avoid dropping the engine... for some reason it's always a hassle to be to work with that mount.

So I took everything apart and yes, the keyway is shot. The bolt was really loose, so that's probably what caused it. The previous owner said he was a mechanic, so I can't even imagine how he could have missed this.
Anyway here the pictures.

I'm clearly gonna need a new key. Both the crankshaft and sprocket are damaged, but only on one side. So maybe if I glue the new key with epoxy I can get away with it? Can I use the good side of the sprocket to align it with the crank or will I need a new one as well?

i've done that before, new key & sprocket and put new key in with some loctide or similar. should be ok.
if you really want to be sure, then weld & file it down till key fitment is correct.
or you can replace crank/engine =) but guessing that not really an option. :huh:

the cause of the broached keyway and woodruff key damage is improper tightening of the bolt.

the key is there merely to ensure proper alignment. the proper torque applied to the bolt is what keeps the pulley in place. when the bolt is loose it works the pulley and key back and forth in the broached slot in the crankshaft and causes that damage. :wink:

So I got another key and sprocket. I used epoxy to glue the key to the crankshaft and installed everything back together.
The car didn't want to start first, because the dissy was still fully advanced. After that it started right away and this time the ignition timing was rock steady at 6 degrees! The car is still misfiring a little bit at idle, but it has old plugs and probably dirty injectors, so that's OK.
I didn't get to test the car on the streets, as I'm also working on the brakes now, but I think the timing issues are solved. If something else comes up after further testing I'll let you guys know. Many thanks to all the people that helped... as usual, Teamswift is the best :D.

jv&s: I don't think working om cars gives me wood :P but it certainly feels awesome to drive the hell out of a car that I fixed myself. I said that I wanted to stop spending time in the garage, but 2 weeks later I bought another GTi! hahaha I can't help it...

janko, just be sure to tighten the bolt down to spec and use loctite to keep it in place.

Fortunately I have a torque wrench, so that that won't be a problem :wink:. Thanks
